Whitelist or Blacklist with a specific IP

I would like to request a feature where we can put in a blacklist or whitelist item tied to an IP. The scenario where I could use this is for a specific device that needs access to a certain ad domain for it to work right. I'd like to basically just allow that domain with that specific IP while leaving it blocked on the rest of my network. I feel like this would be a good feature to have in both directions for both blocking and whitelisting.

This has been asked before, see this thread and all of those linked to it.

Implemented in v5.0 with Group management.
